Struggling with increased costs from a solids handling system as well as decreased productivity due to your pump choking on a regular basis?

Lismore City Council had a daily issue with their pump choking on the number of rags passing through, even after trying different wear plates from different companies. The best they could achieve was to limit choking to once or twice per week by installing one of Gorman-Rupp’s self-cleaning wear plates with a Gorman-Rupp T3A3S-B self-priming pump.

Hydro Innovations introduced Gorman-Rupp’s new Eradicator Solids Management System to the council and they were excited to try it.
The Eradicator™ system features an aggressive self-cleaning wear-plate incorporating a number of notches and grooves, as well as a patent-pending lacerating tooth that helps break up stringy materials (such as rags), scrape them off the impeller vanes and pass them through the pump – all without impacting performance or interrupting service.

A special cover plate with the system also includes a patented lightweight inspection cover that can easily be removed, if necessary, to inspect sewage pump internals.

The Eradicator system is available on all Gorman-Rupp Super T Series wastewater pump models, so the range can achieve flows from 5 LPS through to 150 LPS and deliver heads to 40 metres, all while working on suction lifts to 7.6m.

Because they are self-priming pumps, these sludge pumps can be located at ground level, giving operators easy and safe access to the pumps for monitoring and/or service, unlike submersible pumps which require cranes and several operators to access.

Clearance adjustments, oil changes, and general inspections only take minutes, which adds up to massive savings in time over the life of the pump.

The new system was installed in conjunction with the existing Gorman-Rupp T3.

The sludge pump then ran for 3 months without a single choke.

In the same period, they would have expected to have between 12 and 24 chokes. The entire team at the council were very pleased with the result!
